    CVE ID         : CVE-2019-18224
    Debian Bug     : 942895
    
    A heap-based buffer overflow vulnerability was discovered in the
    idn2_to_ascii_4i() function in libidn2, the GNU library for
    Internationalized Domain Names (IDNs), which could result in denial of
    service, or the execution of arbitrary code when processing a long
    domain string.
    
    For the stable distribution (buster), this problem has been fixed in
    version 2.0.5-1+deb10u1.
    
    We recommend that you upgrade your libidn2 packages.
